Are grid cells used for navigation? On local metrics, subjective spaces, and black holes
G Ginosar, J Aljadeff, L Las, D Derdikman, N Ulanovsky - Neuron, 2023 - cell.com
The symmetric, lattice-like spatial pattern of grid-cell activity is thought to provide a neuronal
global metric for space. This view is compatible with grid cells recorded in empty boxes but …

Locally ordered representation of 3D space in the entorhinal cortex
As animals navigate on a two-dimensional surface, neurons in the medial entorhinal cortex
(MEC) known as grid cells are activated when the animal passes through multiple locations …

Grid cell symmetry is shaped by environmental geometry
Grid cells represent an animal's location by firing in multiple fields arranged in a striking
hexagonal array. Such an impressive and constant regularity prompted suggestions that grid …

Principles governing the integration of landmark and self-motion cues in entorhinal cortical codes for navigation
To guide navigation, the nervous system integrates multisensory self-motion and landmark
information. We dissected how these inputs generate spatial representations by recording …

Shearing-induced asymmetry in entorhinal grid cells
T Stensola, H Stensola, MB Moser, EI Moser - Nature, 2015 - nature.com
Grid cells are neurons with periodic spatial receptive fields (grids) that tile two-dimensional
space in a hexagonal pattern. To provide useful information about location, grids must be …

Connecting multiple spatial scales to decode the population activity of grid cells
Mammalian grid cells fire when an animal crosses the points of an imaginary hexagonal grid
tessellating the environment. We show how animals can navigate by reading out a simple …

A novel mechanism for the grid-to-place cell transformation revealed by transgenic depolarization of medial entorhinal cortex layer II
The spatial receptive fields of neurons in medial entorhinal cortex layer II (MECII) and in the
hippocampus suggest general and environment-specific maps of space, respectively …
